Mutt 1.5.18 (2008-05-17), used with GMail's IMAP, encounters a
segmentation fault in the index menu if the indicator is moved after a
selected folder is kept idle for sometime (< 5 minutes). I have set
imap_keepalive to 240.
Mutt was configured with the following flags on Fedora Core 5 i386 system:
--prefix=/u/debray --enable-pgp --enable-smime --enable-pop --enable-imap
--enable-smtp --enable-hcache --enable-exact-address --enable-locales-fix
--with-ssl --disable-external-dotlock
A bit of playing with GDB gave me the following.
